I've been working on a new project lately, and I just fired it up and I'm amazed. Just to have some fun with this, guess what I did. Your hint is that my Flydragon aspheric (see here) clocked 230 lux in the room I tested this in (ceiling bounce), this mystery light clocked 3400 lux in the same room. This would put it at 14.78 times as bright as my single XM-L2 monster, so maybe 15000 lumens.
Texaspyro and MrsDNF are disqualified from this contest as I have told them about it, if I mentioned it to one of you and forgot please don't post it. ;) The rest of you, I want you to take a guess at the LED(s), the host, the battery, and the driver.
A saft battery like the one they use in Alaska as a backup for the power station in Anchorage (46 megawatt output) powering a liquid nitrogen cooled 12 x SST-90 array at 30 Amps each.
